LOUIS GIIAllIBON, OF PARIS, FRANCE.

MACHINE FOR PRINTING IN COLORS.

SPECIFICATION forming part of Letters Patent No. 626,270, dated June 6, 1899.

Application filed February 19. 1896. Serial No. 579,952. (No model.)

To all whom it may concern.-

Be it known that I, LOUIS CHAMBON, a citizen of the French Republic, residing at Paris, in the Department of the Seine,France, have invented certain new and useful Improvements in Machines for Printing in Colors, of which the following is a specification.

This invention has been patented to me in Great Britain, No. 23,428 of 1895.

My invention relates to a machine in which printing can be effected in an arbitrary number of colors. Itis characterized by the combination of an arrangement of feeding-cylinders placed at the head of the machine, withan arrangement of stretching-cylinders and a cutting apparatus placed at the outlet of the machine, with printing apparatus placed.be-

tween the feeding-cylinders and the stretching-cylinders, the number of the printing devices being equal, to the number of colors to be printed. All of these devices are put in mot-ion by two shafts operated the one by the. other," one carrying the driving-pulley and the operating fiy-wheel and the other a system of helicoidal wheels operating the various elements of the machine grouped in series upon a table of any length. 7

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the machine, parts being shown diagrammatically. Fig. 2 is a top view, partly broken away, with parts in section. Figs. 3 and a show, respectively, sectional views of the feeding apparatus on line C D of Fig. 4 and A B of Fig. 3. Figs. 5 and 6 show, respectively, sectional views of the printing apparatus, Fig. 5 being taken on line G H of Fig. 6, and Fig. 6 on line E -F of Fig. 5. Fig. 7 shows a sectional view of the operating device of the'cam-cylinders and of the inking-cylinders. Fig. 8 shows a moistening device to be applied for lithographin g. Figs. 9 and 10 show, respectively, a sectional view on line I J of Fig. 10 and a plan view of the cutting apparatus. Figs. 10 and 10 are respectively a detail side view and front view of the cutting mechanism on a large scale. Fig. 11 represents a sectional View on line K L of Fig. 9. Figs. 12, 13', and 14: are detail views of the gear-wheelj. Fig. 15 is a detail view of the gearing for operating the cutting apparatus. Figs. 15,15 and 15 are diagrammatic views of the same. Figs. 16 and 17 are detail views illustrating the paperclasps. Figs. 18 and 19 are detail views illustratingthe means for adjusting the printing apparatus laterall-y of the table, Fig. 19 being a section on line 1 2 of Fig. 19.

Upon a table T are grouped the diiferent parts of the apparatus, as shown diagrammatically in Figs. 1 and 2, comprising the feeding apparatus, the printing apparatus, the stretching apparatus, and the cutting apparatus.

The paper to be printed is placed upon a bobbin on the shaft A, provided with a brake A, which may be regulated by means of the rod 13 and screw-button D. The paper'passes over the cylinder C and between the cylinders C and O, which have a diameter appropriate to the length of the sheet to be printed upon, and thence the paper passes between the cylinders D D E E, &c., of the various printing devices, thence between the cylinders G G of the stretching apparatus, and finally into the cutting apparatus II and the receiving-box I.

.Figs. 3 and it show more clearly the distributing apparatus, which consists of three cylinders C C 0 two of which, 0 and 0 have a diameter corresponding exactly with a design to be printed. One of the cylinders, C, is operated by the helicoidal gearing c driven by the endless screw or worm c, mounted upon the driving-shaft J, and motion is transmitted to the upper cylinder (3 by means of the gear-wheels c 0 The lower cylinder 0, fitted with a leather or rubber cover 0 is pressed tightly against the cylinder C by means of the levers c, which maybe adjusted by means of the screws c so as to correspond with the varying diameters of the feedingcylinders. The cylinders C and C -may be changed by removing one of the sides T,

ed upon a bottom piece S, with'which they are connected by means of screws V and dowels v, which assure perfect fitting in repin H passing between the armsj carried by the plate D this pin being'pressed upon by adjusting-screws 7' 7' threaded through WVhen it is desired to give the cylinder any considerable amount of adjustment in relation to the worm-wheel j and driving-worm j in order to bring the printing-cylinder into proper relation to the paper to be printed,

'the screws E are loosened, when the areshaped slots permit the shaft and plates to be rotated to any desired distance within the limits determined by the length of the slots.

Should a very small and accurate adjustment be found necessary, this may he accomplished by adjusting the screws 7' bearing against the pin H The pressure between the cylinders D and D is produced, as in the feeding apparatus, by means of a system of levers c and the screw o which in order to make said pressure-yielding may-be supported upon a flexible abutment, as shown in Fig. .5, a stopscrew 0 being provided at the other end of the lever to limit the upward movement of the cylinder.

The cylinder D which is operated by the cylinder D through the gearing d d d d which latter is connected to the cylinder D by pin TX, serves as an inking-table, and a reciprocating motion'is imparted thereto by the pin 0', carried by-the cylinder,.which presses constantly upon the cam R of the shaft R by means of the spring'r The shaft R is driven by the gear-wheel Z fixed on the end thereof, engaging with. the gear d, and the relative size and arrangement of the gearsd d and (Z (Z are such-that the shaft R is caused to rotate at a different rate of speed from the cylinder D so that the endwise movement of the cylinder D due to the action of the cam will be constantly varied with relation to the surface of the ink-supplying rollers O O and the inktransferring rollers D and D and hence a much more uniform distribution of the ink secured.

' The ink-transferring rollersD andD, coat ed with gelatin, as indicated-by dotted lines fz; Fig, 5,-are mounted upon azgles 22 in the rocking arms Z Z and are pressed by the tension of springs e 2 constantly against the rollers or cylinders D and D so that they receive ink from the roller 1) and transfer it to the roller D. The-cylinder D receives the ink from the two rollers O O, freely movthe fastening-screws Z pass.

able in grooves 0, and a third roller 0 con-- nected by links to the axle 0, takes ink from the inking-cylinder 0 in order to transfer it to the roller O by its contact therewith, the

roller 0 in turn supplying the ink to the rollers O and O. A roller 0 mounted upon an axle that slides freely in the grooves o,- spreads uniformly the ink received by the table or roller D The roller 0? is carried by theshaft 0, journaled in the end of links or .levers L, and forms therewith and with the Y axle l a frame which is operated by the camroller- Z and'the cam Z and will thus impart during its'motion a reciprocating motion to the roller 0 similar to that of the cylinder D which motion will enable the roller to equal ize the ink it deposits upon the rollers O and O. The receiving-roller O is operated by the cam M and the roller m, mounted upon the piece M, which also carries the pawl m, serving for actuating the ratchet m mounted upon the cylinder 0 which revolves in the inkereservoir-mi The regulating of the contact between the inking-roller O and the cylinders O and O is obtained by the screw m pressing upon a small lever 122 which, togetherwith the lever m is rigidly fixed upon the axle o.

In order to clean the inking-rollers and the cylinders, the upper part of the uprights are removed, which parts are connected by two rods 1. 15, carrying dowels 15 i which insures the accurate replacing of the removed parts.

A screw '0 acting upon an abutment V fixed in the table, permits the lateral adjust ment of the printing apparatus by means of the elongated openings '0 v in the bottom piece S, through the latter of which openings (See Figs. 18 and 1-9.)

If desired, supportingand feeding cylinders (1 may be provided for supporting and guiding the paper as it leaves the printing-cylinder, as indicated in dotted lines on the left of Fig. 5.

When the machine is used for lithographing-workthat-is, when the cylinder D is made of lithographing-stoneit is necessary that provision be made for washing the same.

To this end I use a moisteningapparatus, ap-

IIC

plied in the position indicated by the dotted circle P in Fig. 7 and shown in. detail in Fig. 8. This comprises a trough .P, filled with water, in which av moistening-cylinder P in contact with the cylinder D, revolves. The trough P is fed by a'fiask P the neck of which is reversed into the liquid, thus maintaining a constant level, as the instant the level of the water in the trough falls below the neck of the flask the air willpass into the flask, permitting the water to flow down into the tank to raise the level up to the neck of the flask; The upper end of the flask is 7 closed by a screw-stopper P of the casing-.boi:

P which makes the filling thereof easy. I

The stretching apparatus is very similar to the feeding apparatus, and consists, essentially, of two cylinders G G, the former of Which,G,has a diameter slightly greater than that of the cylinder 0, so that it produces a constant stretching of the paper. It is operated by the shaft Jthrough the intermediary of the helicoidal gearing g g. The pressure of the cylinder G can be regulated by means of the levers g and the screws g The cutting apparatus, Figs. 9, 10, and 15, comprises the cutter II, fixed upon an oscillating rod 71-. It presses constantly by means of the spring K against the counter-cutterK or upon the guide K, which' is the vertical prolongation of the edge of said counter-cutter. The cutter H is operated by the rods h, linked upon the levers 7L2 and operated by the disks 71.3. A sliding piece or bracket 7& serves for changing the relation of speed of the shafts 71, and h (the latter of which is driven from the shaft J) by means of the gearing 7&7 h 769, having variable diameters, thus permitting the cutting ofthe paper into varying lengths, according to the requirements of the work and size of printing-cylinders employed. A

- ingrcylinders employed.

shaft N (see Figs. 10, 1 O-, a nd 15, 15.", 15",

and 15) is journaled in the rocking piece h which rocks about the shaft its as a center and is held in its adjusted position by a boltMtL passing through a slot M and engaging a stationary part of the table or frame. This shaft N carries two gears It -and h the former of which engages constantly with the gear h" on the shaft h The shaft h carries a removable gear 7L7, so that a small gear may be placed thereon to engage with gear h or a large gear which will engage directly with gear 71. the piece 7L being adjusted according to the size of the gears, as clearlyindicated in Figs.

15, 15, and 15. A removable piece h spaces the gear h the latter being held in place by a nut J Itwill thus be seen that by changing the gearing, as above described, the knife may be made to reciprocate more or less quickly to cut the paper into longer or shorter strips, according to the diameter of the print- Circular cutters H II and corresponding counter-cutters H H, Fig. ll, can also be mounted upon the shafts II II at any point in order to cut the paper into acorresponding number of bands. A

A plate N, fixed upon the lever 92, which is operated by the cam n and'the roller n extends over the entire width of the machine, and during the cutting it presses the paper "upon the fixed clasps n adj ustably carried on the transverse rod T and may be regulated or adjusted not to touch the printed parts. p

- The parts at, a and 'n constitu te the paperfeed. To that end they are arranged in the following manner: The part it consists of a cylinder or roller of smooth steel, the shaft of which is actuated by the gearing shown and has a quicker motion than the normal movement of the paper, so as to prevent the bulging of the paper occurring in the continuous run ofthe same when it is momen tarily stopped for cutting by means of the duced at such moment behind these parts on account of the stop.

02 n are two rollers covered with rubber and mounted on aloose shaft. These two rollers can be adjusted in position so as to rest only on the unprinted parts of the paper. They are rotated by the paper in its advancement and are at rest when the paper stops.

"lhe part a glides on the paper when it steps or when it travels atits normal speed, as it is understood that its speed is greater part is made of smooth steel, the sliding along is easy. After a momentary stop of the paper for cutting the paper moves at the same speed as the roller n" until any bulges in the paper that may have formed have been removed.

The parts N n serve to procure the momentary stop of the paper, so as to allow the knife H to act perpendicularly and at right angles to the travel of the paper, which would not be the case if the paper would travel on during the cut, as in that case the cut would be on the bias. These parts N n are arranged as follows: a designates stationary platens perrnanently mounted on their shaft and which can be adjusted at will, so as to have them rest onthe unprinted parts of the paper, which 'varyaccording to the width of paper used. \"Vhile the paper advances, these platens are not in contact with the paper, though the space between plat-ens and paper is very small. necessary to raise the piece N slightly. By

tweenthe piece N and the platens 41 which may be lined with felt or rubber for the pose of obtaining a better grip.

The operation of the part N is very simple. It consists, essentially, of a lever 17., carrying at its extremity a roller n actuated by the cam n, the corresponding bosses and flats of which vibrate the piece N on its axis, and thereby lift its longest end in such a manner that it grips the paper on the piece or the pieces a" owing to its felt covering. There can be no twisting of the paper inducedby and N, as during the stop of the paper produced by the action of the parts n and N the part a simply glides on the paper and the parts a a are stationary.

The cut sheets are deposited upon a bracket or table I, sliding vertically in a box I. In order to automatically lower the table as the leaves are placed upon it, a screw '5' is provided, carrying a worm-wheel 2' which engages a driving-worm '6 The bracket or table is connected to a guiding-block 2', which has a smooth opening through which the screw passes. A bell-crank leverl is pivoted to a portion of the block 1' beneath thetable, one end serving as a handle and the other To stop the paperfit. is only this slight raise the paper will beheld be the combined action of the parts a, n 91 ,01

carrying a threaded half-block i, which enorgans or parts N n3, such bulging being prothan the normal speed of the paper. As this s purgages the thread of :the screw 11' and lowers the table as the screw rotates. By means of I the handle the half-block may be readily dispart of the present invention it is not deemed necessary to describe it in detail.

The parts of the machine thus described are operated by means of the two longitudinal shafts J. J, of which one, J, carries the driving-pulley and fly-wheel, while the other, J, driven from the shaft J by interposed gearing, carries the worms foroperating the wormwheels', and through them the variousparts previously described, thus causing all the cylinders to be driven simultaneously at a uniform rate of speed.

The driving-pulley carried by the shaft J is a friction-pulley, and the engaging and disengaging are accomplished in the following manner: To start the machine, the bar Y is pushed from left to right by meansotthe handles y, arranged at various points on the bar, so that the operator may throw themachine in gear at various points. This action" results in the tenon Y pushing barY to the right and throws the friction-cone of the pulleyinto contact ther with; The engagement is maintained 1 ean's of the lever 1 actuated by a spring 1J which forces-it against the heel j. "To disengage the mechanism,
